Printing 2 half landscape page in 1 letter size sheet using ITextSharp

Question

I'm Generating my PDF file using MvcRazorToPdf and ITextSharp. My code is like this:

public ActionResult Print()
{
    var model = new recordListModel();
    model.records = db.Records.Select(x => new recordModel { 
        Id = x.Id,
        Date = x.Date,
        PaidTo = x.PaidTo,
        CheckNo = x.CheckNo,
        Payor = x.Payor
    }).ToList();

    return new PdfActionResult(model, (writer, document) =>
    {
        document.SetPageSize(new Rectangle(612f, 396f, 90));
        document.NewPage();
    });
} 

When PDf is generated it will display for example 2 landscape pages that is a half of letter size sheet that you will see in this line of code:

document.SetPageSize(new Rectangle(612f, 396f, 90)); // half of letter size

But when i print it the first page is printed in a whole sheet and the second page also printed in a whole sheet.

How can i print this 2 landscape pages in one sheet? Thanks in advance.
